Pre-curse information:
Wendy had been living a somewhat calm life back in London with her brothers, occasionally they had to look over their shoulders but nothing bad happened to them.
A thing she hid from her siblings was her deep need to get revenge on Peter for all what he had done to her even though he was supposed to be dead.
Wendy wanted to stay like they were and never go back to Storybrooke again but obviously she didn't get her wish.
Post-curse information:
Wendy is trying to dodge her son, even though he doesn't know who she is, it's to avoid awkwardness.
Wendy didn't even think she would have kids in fear of losing them the way her parents lost her.
Wendy has a small part of her that hopes Peter will show up for way different reasons than revenge and is currently shoving that part of herself way down.
Wendy currently lives in a motel and is trying to get her life back in order.
